Abstract: An article formed of a metal alloy is covered at least partially with a metal hydride and a shell metal to form an assembly. Load is applied to the assembly and the assembly is heated. The shell metal deforms around the article and the metal hydride and forms a gas proof seal. The metal hydride thermally decomposes to form hydrogen gas. At least a portion of the hydrogen gas dissociates and moves as monoatomic hydrogen into the article. The metal alloy can be a zirconium metal alloy, the metal hydride can be a zirconium metal hydride, and the shell metal can be substantially copper.

Abstract: The present concept is a compact portable colour sensor for measuring colour of a substrate. The sensor includes a lower and upper housing, and a detector portion. The detector portion includes a printed circuit board connected to an interior of the housing. The circuit board includes at least one LED and one colour sensor mounted on a bottom side thereof. At least one transparent light transmitting light pipe and a transparent material are mounted interferingly between the bottom side of the printed circuit board and the interior of the lower housing. The compact portable colour sensor is configured such that light transmitted by the LED impinges upon the substrate through a light cavity, and is at least partially reflected back to the colour sensor to take a measurement. Preferably the lower housing has an inverted truncated conical shape.

Abstract: The present concept is a compact portable colour sensor for measuring colour of a substrate. The sensor includes a lower housing including an interior, the lower housing for cooperatively mating together with a upper housing, a detector portion including a printed circuit board rigidly connected to an interior of the lower housing and substantially enveloped by the upper and lower housings when in a mated position The printed circuit board includes at least one LED and one colour sensor mounted on a bottom side of the printed circuit board, and at least one transparent light transmitting light pipe and a transparent lens is mounted interferingly between the bottom side of the printed circuit board and the interior of the lower housing, and wherein the compact portable colour sensor is configured such that light transmitted by the LED impinges upon the substrate and is at least partially reflected back to the colour sensor to take a measurement.
